docs: sort-imports add single named import example (eslint#15675)

Added examples of a single named import. Clarifying that it should be grouped with the default/single imports and not with the named/multiple imports.

I find the current behavior confusing and so do others eslint#14259 eslint#14570 eslint#14735 eslint#13655 eslint#13222 eslint#11159 eslint#10878.
